Spark Gap Switches

Pure tungsten is preferred for electrode use as it does not oxidize or require cleaning. Its intrinsic low resistance allows the electrodes to run cooler. Tool steel will perform reasonably well for Tesla coils but will run hotter and consequently not quench the spark as well as tungsten.

This model of spark gap is used in many classified projects at Los Alamos National Laboratories

Applications

High powered pulse forming networks

Pulsed laser drivers

High peak current injection

Safety discharging capacitor banks

Marx inter-stage capacitor series switching

Many high voltage switching applications

The Triggered Spark Gap Switch discharges stored capacitor bank energy by way of an adjustable spark gap switch. It can be manually fired with a pushbutton switch, or set to auto-discharge at a specified voltage. An extension wire allows the operator to stand 10 feet or further away if safer manual ignition is required.

External connection lugs are heavy duty #6 block lugs with set screws assuring a positive connection. All connection lugs are positioned to help reduce power robbing stray inductance. Input power is 12V DC at 100mA.

FEATURES: • Triggered 3/8" Tungsten Electrode Spark Switch, Up to 3 kilojoules at 10 kilovolts into proper load • Uses heavy duty rectifiers and a dv/dt protection resistor with high u ferrite cores to direct hv trigger pulses • #6 block lugs are used for all high current connections; wire size is 8 to 12 gauge • All high current, high voltage carrying leads are sleeved into insulating polypropylene tubing • Data is included that shows disconnection methods between controller/charger & storage capacitors for energies over 3000 J

Built-in trigger circuit initiates discharge by a 12 volt DC level.

This Triggered Spark Gap Switch is used as part of our HEP50 and HEP100 High Energy Pulser systems.

Intended for Tesla coils up to 15Kv at 180ma. Available with 3/8" machined tool steel or pure tungsten electrodes. Functions at 60 to 100 breaks/second. There are 3 electrodes: the 1 center electrode is 2.5" length; the 2 side electrodes are each 2" length. 115 Vac is required for the high output fan. Ready to use with connection lugs. Size is 5 x 5 x 4". Our BTC40, 50, and 60 use this setup.

Use two in series for a four point gap for Tesla power up to 15kV at 400ma producing up to 15’ sparks. Our BTC70 uses this setup.

We also carry solid copper block holders or the more attractive PANDUIT holders. We tested for temperature rise and peak current and found no difference between the lower cost aluminum or copper holders.

These are manufactured in Bangalore by a very reputable company that is sanctioned by many governments including the US. Products are made from top-quality materials and are precision made to stringent specification. If you do not see what you need please use contact form for your specs.

MODEL# IU26123TSG

Three terminal triggered spark switch. This high-powered unit has a self breakdown voltage rating of 26kV. And a current rating of 10 to 12kA. This equates out to a peak power in excess of 300 MW! Quality made part was an over run from a government contract costing over $1000 each. They are used on a small handheld EMP pulse gun experiment. We have a limited amount and can offer them to you for $696 each. See our many other spark switches on this page.
